In 2011 the European Centre for Disease Prevention and Control (ECDC) initiated a Europe-wide Point Prevalence Survey (PPS) to measure healthcare-associated infections (HAI) and antibiotic usage (ABU) in hospitals. We implemented this survey in Germany to examine countrywide HAI and ABU prevalence data for acute care hospitals.


The ECDC developed a protocol for the implementation of the PPS in different European countries introducing standard definitions of HAIs and of ABU. We chose a representative sample and invited hospitals from the German national nosocomial infection surveillance system to participate on a voluntary basis. The survey period was from September to October 2011.
We created Case Report Forms (CRFs) for hospitals, units, and patients, and established a method to identify the CRFs in an Optical Character Recognition system. We also trained local hospital infection control personnel (ICP) in the PPS method including the diagnosis of HAIs. The ICPs had to fill out a patient CRF for each patient with HAI and each patient with ABU respectively.


A total of 138 hospitals with a median bed size of 332 participated in the PPS. 38,771 patients were examined, of which 2,538 patients were diagnosed with a HAI. The overall HAI prevalence was 6.1% whereas the prevalence of infections explicitly acquired in hospitals was 5.3%. The highest prevalence of HAI was in intensive care units (21.3%), followed by rehabilitation (19.6%) and geriatrics (8.8%). The overall ABU prevalence was 27.8%. ABU is subdivided  into: 50% to treat community based infections, 19% for in hospitals acquired infections and for prophylaxis 31%. In large hospitals with more than 800 beds, HAI prevalence was 6.6% and ABU was 30.3%. In hospitals with less than or equal to 800 beds, the prevalences were 5.9% and 26.7%, respectively.


The PPS was successfully executed and the paticipating hospitals were highly committed. The HAI results of the German PPS are in the range of the published European prevalence surveys with prevalence values from 4% to 7%.
